Battle! Dante vs. Squall

That's damn near what FF10 does for the characters. If you compare them, without translation, to a character from any other RPG, the FF10 character annhiliates them.

In a general, 45 hour game of FF 10, the characters can at least compare with those of other games. However, after 55 hours or so (depending on how well one utilizes the Battle Arena), any character on FF 10 becomes virtaully unbeatable. In addition, neglecting Overdrives and the ability to summon, (take note here) every character is exactly the same after leveling up (quickly via the Battle Arena).
